To do.

車両２と通信しながらガス（例えば水素ガス）を充填する通信充填対応のガス供給ステーション１は、ガスステーションディスペンサ１ａ、ステーション側圧力センサ１０、充填ノズル１１を備えている（図１参照）。充填ノズル１１は車両２のレセプタクル２３に接続される。圧力センサは、ガス充填時のディスペンサ１ａ側圧力Ｐ０を検出する。   The gas supply station 1 for communication filling that fills gas (for example, hydrogen gas) while communicating with the vehicle 2 includes a gas station dispenser 1a, a station-side pressure sensor 10, and a filling nozzle 11 (see FIG. 1). The filling nozzle 11 is connected to the receptacle 23 of the vehicle 2. A pressure sensor detects the dispenser 1a side pressure P0 at the time of gas filling.

車両２は、１個以上、一例として２個のガス貯蔵タンク（図１で３１ａ，３１ｂというようにａ，ｂの添字を付して示す。２個ある他の部材も同じ）、該ガス貯蔵タンク３１ａ，３１ｂにガスを充填し、充填されたガスを車両搭載の動力機関（例えば燃料電池）に供給するためのレセプタクル２３、充填系マニホールド２４、供給系マニホールド２６等からなるガス貯蔵装置を備えている。   The vehicle 2 has one or more, for example, two gas storage tanks (indicated by subscripts a and b such as 31a and 31b in FIG. 1. The same applies to the other two members), the gas storage A gas storage device including a receptacle 23 for filling the tanks 31a and 31b with gas and supplying the filled gas to a vehicle-mounted power engine (for example, a fuel cell), a filling system manifold 24, a supply system manifold 26 and the like is provided. ing.

ガス貯蔵タンク３１ａ，３１ｂのバルブ２７ａ，２７ｂには、充填系の逆流防止弁となる逆子弁２８ａ，２８ｂと、ガスを下流（図示しない減圧弁のある側）へ供給するための主止弁２９ａ，２９ｂとが設けられている。主止弁２９ａ，２９ｂは、システムの起動・停止に併せてオン・オフする。また、ガス貯蔵タンク３１ａ，３１ｂの内部には、タンク内温度を測定する温度センサ３０ａ，３０ｂが設けられている。   The valves 27a and 27b of the gas storage tanks 31a and 31b include reverse valves 28a and 28b serving as backflow prevention valves for the filling system, and a main stop valve 29a for supplying gas downstream (on the side having a pressure reducing valve not shown). , 29b. The main stop valves 29a and 29b are turned on / off as the system is started and stopped. Further, temperature sensors 30a and 30b for measuring the temperature in the tank are provided inside the gas storage tanks 31a and 31b.

レセプタクル２３から充填されたガスは、充填系マニホールド２４を介し、バルブ２７ａ，２７ｂ内の逆止弁２８ａ，２８ｂを通ってガス貯蔵タンク３１ａ，３１ｂ内へ充填される。充填系圧力センサ２１は、充填時のガス圧（Ｐ１圧）を検出する。   The gas filled from the receptacle 23 is filled into the gas storage tanks 31a and 31b via the filling system manifold 24 and the check valves 28a and 28b in the valves 27a and 27b. The filling system pressure sensor 21 detects the gas pressure (P1 pressure) at the time of filling.

ガス貯蔵タンク３１ａ，３１ｂに充填されたガスは、主止弁２９ａ，２９ｂを開くことにより、供給系マニホールド２６を介して、車両２の減圧弁へと送り込まれ、減圧後、動力機関に供給される。供給系圧力センサ２２は、供給時のガス圧（Ｐ２圧）を検出する。   The gas filled in the gas storage tanks 31a and 31b is sent to the pressure reducing valve of the vehicle 2 through the supply system manifold 26 by opening the main stop valves 29a and 29b, and is supplied to the power engine after the pressure is reduced. The The supply system pressure sensor 22 detects the gas pressure (P2 pressure) at the time of supply.

圧力センサ２１，２２による検出データ、および、ガス貯蔵タンク３１ａ，３１ｂ内の温度センサ３０ａ，３０ｂによる測定データは、ＥＣＵ（電子制御装置）２５へ送信される。また、ＥＣＵ２５は、各ガス貯蔵タンク３１ａ，３１ｂの主止弁２９ａ，２９ｂに対して開閉信号（オン・オフ信号）を送信する。さらに、ＥＣＵ２５は、車両２へのガス充填時、ガスステーションディスペンサ１ａと通信する。   Detection data by the pressure sensors 21 and 22 and measurement data by the temperature sensors 30a and 30b in the gas storage tanks 31a and 31b are transmitted to an ECU (electronic control unit) 25. The ECU 25 transmits an open / close signal (on / off signal) to the main stop valves 29a, 29b of the gas storage tanks 31a, 31b. Further, the ECU 25 communicates with the gas station dispenser 1a when the vehicle 2 is filled with gas.

本実施形態における圧力センサ２１，２２の異常診断システムは、以下のようにして診断をする（図２、図３参照）。   The abnormality diagnosis system for the pressure sensors 21 and 22 in the present embodiment diagnoses as follows (see FIGS. 2 and 3).

１）車両側 充填系圧力センサ２１の異常検出
通信充填時、充填系のガス圧データ（Ｐ１圧）は車両２側のＥＣＵ２５を経由してガスステーションディスペンサ１ａ側へ送信されて監視されている。満充填終了直前、ガス流量が予め設定した値に到達したら、異常判定を行う（図２のステップＳＰ１）。また、このとき、充填系圧力センサ２１によるＰ１圧は、ＥＣＵ２５にメモリされる（ステップＳＰ７）。 1) Abnormality detection of vehicle side filling system pressure sensor 21 During communication filling, gas pressure data (P1 pressure) of the filling system is transmitted to the gas station dispenser 1a side via the ECU 25 on the vehicle 2 side and monitored. Immediately before the end of full filling, when the gas flow rate reaches a preset value, abnormality determination is performed (step SP1 in FIG. 2). At this time, the P1 pressure by the filling system pressure sensor 21 is stored in the ECU 25 (step SP7).

異常判定は、ディスペンサ側の圧力であるＰ０圧と車両２側のＰ１圧との差圧は、通常であればほとんど無くなるという前提で行う。すなわち、ある程度の誤差αを考慮しておき、｜Ｐ０−Ｐ１｜の値が誤差αを上回っていれば充填系圧力センサ２１に異常があると判定し（ステップＳＰ３）、誤差αを上回っていなければ正常であると判定し（ステップＳＰ４）、充填を終了する（ステップＳＰ８）。異常があると判定した場合には、この場合、ディスペンサ１ａ側にて画面表示や音声などで異常を知らせ、当該圧力センサ２１の交換を促し（ステップＳＰ５）、充填を終了する。なお、本実施形態では、充填系圧力センサ２１に異常があると判定した場合には、後述する供給系圧力センサ２２の異常検出（図２に示すフローの右側）は行わない。   The abnormality determination is performed on the premise that the differential pressure between the P0 pressure, which is the pressure on the dispenser side, and the P1 pressure on the vehicle 2 side is almost eliminated if normal. That is, taking into account a certain amount of error α, if the value of | P0−P1 | If it is normal, it is determined to be normal (step SP4), and the filling is terminated (step SP8). If it is determined that there is an abnormality, in this case, the abnormality is notified on the dispenser 1a side by a screen display or voice, etc., prompting replacement of the pressure sensor 21 (step SP5), and filling is completed. In this embodiment, when it is determined that there is an abnormality in the filling system pressure sensor 21, an abnormality detection (right side of the flow shown in FIG. 2) of the supply system pressure sensor 22 described later is not performed.

２）車両側 供給系圧力センサ２２の異常検出
充填終了直前のＰ１圧とタンク内温度Ｔ１をＥＣＵに記憶しておく（ステップＳＰ７）。充填終了後の最初の車両起動（なお、このとき主止弁２８ａ，２８ｂは開）をしたら（ステップＳＰ９）、ＥＣＵ２５にて記憶しているＰ１圧を温度（充填時温度Ｔ１、起動時の温度Ｔ２）により補正する（ステップＳＰ１０）。その後、｜Ｐ１補正値−Ｐ２｜の値が、予め設定しておいた誤差βを上回っていれば供給系圧力センサ２２に異常があると判定し（ステップＳＰ１２）、ダイアグノーシス（自己診断機能）により異常を知らせ、当該圧力センサ２２の交換を促す（ステップＳＰ１３）。一方、｜Ｐ１補正値−Ｐ２｜の値が、予め設定しておいた誤差βを上回っていなければ異常検出処理を終了する。 2) Abnormality detection of vehicle-side supply system pressure sensor 22 P1 pressure and tank internal temperature T1 immediately before the end of filling are stored in the ECU (step SP7). When the vehicle is started for the first time after completion of filling (the main stop valves 28a and 28b are opened at this time) (step SP9), the P1 pressure stored in the ECU 25 is set to the temperature (filling temperature T1, starting temperature). Correction is performed by T2) (step SP10). Thereafter, if the value of | P1 correction value−P2 | exceeds the preset error β, it is determined that the supply pressure sensor 22 is abnormal (step SP12), and diagnosis (self-diagnosis function) is performed. To notify the abnormality and prompt the user to replace the pressure sensor 22 (step SP13). On the other hand, if the value of | P1 correction value −P2 | does not exceed the preset error β, the abnormality detection process is terminated.

なお、供給系圧力センサ２２の異常検出処理は、充填側圧力センサ２１が正常な場合に限る。したがって、充填側圧力センサ２１に異常があると判定した場合には、上述したように供給系圧力センサ２２の異常検出処理は行わない。   The abnormality detection process of the supply system pressure sensor 22 is limited to the case where the filling side pressure sensor 21 is normal. Therefore, when it is determined that the charging side pressure sensor 21 is abnormal, the abnormality detection process of the supply system pressure sensor 22 is not performed as described above.

なお、上述の実施形態は本発明の好適な実施の一例ではあるがこれに限定されるものではなく本発明の要旨を逸脱しない範囲において種々変形実施可能である。   The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention.

本発明は、ガス貯蔵装置の圧力センサの異常を診断する異常診断システムに適用して好適である。   The present invention is suitable for application to an abnormality diagnosis system for diagnosing an abnormality in a pressure sensor of a gas storage device.
